SPECIFICATION forming part of Letters Patent No. 2749,866, dated March 27, 11883.

Application filed May 7, 1881. Renewed December 1, 1882 (No model.)

I To all whom it may concern Be it known that I, ALFRED WANNAMA- KER, a citizen of the United States, and a resident of West Salem, in the county of Wayne and State of Ohio, have invented a new and useful Improvement in Flax-Thrashers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 is a cross-sectional view of the machine. Fig. 2 is a view, partially in section, of the sectional yielding roller. Fig. 3 is an nner face view of one of the disks I. Fig. 4 1s a plan view of one of the springincasing sections of which the cylinder D is composed.

Fig. 5 is a plan view of the modified rubber spring h. Fig. 6 is a vertical sectional view of the cap or incasement shown in Fig. 4. Fig. 7 isa plan of the block used in connection with the segment-springs H and the cylindrical section Gr. Fig. 8 represents one of the segment-springs; and Fig. 9 is an end or face new of the incasement G, block F, and segment-springs H shown in connection prior to being placed in position upon the shaft E.

'lhisinvention has relation to flax-thrashers for saving the seed, and is used in connection with agrain-separator; and the invention consists 1n the construction and novel arrangement of parts, as will behereinal'ter fully described, and particularly pointed out in the claims appended Referring byletter to the accompanying drawings, A designates the frame; B, the housing; 0, the solid lower cylinder,and D the upper secti onal cylinder.

E designates the shaft ofthe sectional oyl' inder D, which cylinder is composed of yielding sections, constructed as hereinafter explained.

L designates-the feed-chute, through which the seed-flax is fed to the cylinders.

M designates the beater-board, located at a point where the seed-flax, which is fed forward by the cylinders (J and. D, will receive theblows from arevolving beater, N, as shown in thedrawings.

periphery of one of the sections of the yieldin g cylinder D, and g is a vertical flange ex tendinginwardly at aright angleto the peripheral flange g.

H designates rubber springs having curved outer edges to fit the curve of the flange g, and piano bases to meet plane surfaces on the blocks F upon the shaft E.

A modification of this construction is shown in Figs. 4 and 5, wherein the block F and springs H are dispensedwith, and the capG is provided'with dovetail slots g and curved bearings 9 and'a rubber block, It, adapted to fit into this conformation, and permit the section thus formed to he slid upon the shaftE, is substituted. In either case a yielding section is formed-when in place upon the shaft E.

After these sections are formed and slipped upon the shaft E the dovetail slots or notches g are brought into alignment, and horizontal keys or strips K are passed through the inder D,whicl1 may be then placed in position in the housing B. The rollers or cylinders G and D may be driven by gearing of any suitable kind. The object of making the uppercylinder of yielding sections is to permit bunches of seed-flax of varying sizes to pass between it and the lower cylinder without clogging or straining the mechanism.

. As before stated, this device is to be used in connection with a grain-separator.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a flax-thrasher, a cylinder composed of yielding sections consisting of cylindrical caps G, springs, H, perforated block F, the

stantially as specified. of two witnesses. i

2. The combination with the shaftE of a v 5 roller-section composed of the cap G, having ALFRED ANNAMAKER' the flange g, and. an annular spring-support Witnesses:

incased therein and. adapted. to be slipped JOHN FASIG, upon the shaft, substantially as specified. JAMES STEVENSON.
